Description

[Technical Field]

[0001] The present invention relates to a solar panel installation structure and a solar panel installation method, and more particularly to a solar panel installation structure and a solar panel installation method that, when installing solar panels on the roof of a building, do not require special installation processing on the roof floor, can sufficiently prevent the solar panels from moving even when an external force is applied, and allows for stable placement. [Background technology]

[0002] In recent years, with the promotion of the use of renewable energy, there has been an increasing demand for installing solar panels on rooftops of buildings.

[0003] When installing solar panels on the roof of a building, it is common to have a structure in which the floor slab that forms the rooftop floor and a dedicated concrete foundation are installed as an integrated unit from the beginning of construction. The solar panel mounting base is fixed to this dedicated concrete foundation using anchor bolts, etc.

[0004] In this way, a structure in which a dedicated concrete foundation is installed integrally with the floor slab from the beginning of construction allows for the solar panels to be firmly fixed in place so that they can withstand wind pressure during strong winds, etc. Also, since there is no need to attach anchor bolts or other fixing devices directly to the floor slab on the building's roof, it is possible to protect the waterproof layer installed on the roof floor surface.

[0005] On the other hand, there are cases where solar panels are installed on buildings that were not originally designed to have solar panels on their roofs.

[0006] In such cases, since there is no dedicated concrete foundation on the roof, anchor bolts or other fixing devices are driven directly into the roof floor slab to secure the support frame for the solar power panels to the floor slab.

[0007] Thus, when installing anchor bolts or other fixing devices on a rooftop floor slab, the existing waterproofing layer applied to the surface of the floor slab must be partially removed or holes must be drilled, and then new waterproofing work must be applied to that area.

[0008] Furthermore, when new waterproofing is applied to the floor slab, a joint in the waterproof layer is created between the existing applied area and the area applied later.

[0009] Not only does this joint in the waterproofing layer pose a risk of water leakage, but it also invalidates the validity of the waterproofing guarantee provided by the waterproofing contractor for the existing waterproofing work, causing disadvantages to the building manager.

[0010] In this context, a method has been proposed that attempts to stably install solar panels on the floor slab of a building's roof without driving anchor bolts or other fixing devices into the floor slab, while maintaining the performance of the waterproof layer of the floor slab (see, for example, Patent Documents 1 and 2).

[0011] Here, in the solar power generation panel installation stand described in Patent Document 1, mounting parts are provided on non-floor areas on the roof of the building on both sides where the solar power generation panels are placed, and a string-like object with both ends attached to the mounting parts is stretched between these mounting parts.

[0012] The string-like material contacts the entire light-receiving surface of the solar panel from one end to the other, and this string-like material suppresses the lift force applied to the solar panel by strong winds, etc., and secures the solar panel in place.

[0013] In addition, the solar panel installation stand described in Patent Document 2 has a structure in which multiple mounting frames are fixed to the floor of the roof of a building with adhesive, and these mounting frames support the solar panels, with multiple cover walls installed around the mounting frames.

[0014] In the solar power generation panel installation stand described in Patent Document 2, a cover wall installed around the periphery of the stand prevents wind from blowing under the solar power generation panels, thereby preventing the solar power generation panels from flying away. [Prior art documents] [Patent documents]

[0015] [Patent Document 1] Patent No. 6296222 specification [Patent Document 2] Patent No. 6219450 specification Summary of the Invention [Problem to be solved by the invention]

[0016] Here, the solar panel installation stand described in Patent Document 1 is effective against vertical external forces induced by strong winds, etc., but is insufficiently fixed when horizontal external forces are applied due to earthquakes, etc.

[0017] In other words, when a horizontal external force due to an earthquake or the like acts on the solar panel installation stand, the friction caused by the tension of the string-like material against the light-receiving surface of the solar panel acts as the main deterrent, but this alone is not enough of a fixing force, and there is a risk that the solar panel will move significantly horizontally.

[0018] Furthermore, in the solar panel mounting base described in Patent Document 2, exposure to wind, rain, etc. will cause the adhesive to deteriorate rapidly over time, and it is expected that the strength of the mounting base to the rooftop floor will be lost in a short period of time.

[0019] Furthermore, in the solar panel installation stand described in Patent Document 2, the provision of a cover wall reduces ventilation around the solar panel stand, making it easy for the solar panels to reach high temperatures. As a result, there is a problem in that the surface temperature of the solar panels rises and the power output decreases.

[0020] The present invention has been devised in consideration of the above points, and aims to provide a solar power panel installation structure and a solar power panel installation method that, when installed on the roof of a building, does not require special installation processing on the roof floor, can sufficiently prevent solar power panels, etc. from moving even when an external force is applied, and can be stably positioned. [Means for solving the problem]

[0021] In order to achieve the above-mentioned object, the solar power panel installation structure of the present invention is a solar power panel installation structure for installing a solar power panel on the floor surface of a building that is fixed to the floor surface of a roof and has a predetermined rising portion that rises upward from the floor surface, and includes a panel support portion that supports the solar power panel at a predetermined inclination, and a floor installation portion that is a metal material of a predetermined length that is placed on the floor surface and has one or both ends fixed to the predetermined rising portion and is fixed to the panel support portion, and supports the panel support portion.

[0022] Here, by having the panel support portion support the solar power generation panel at a predetermined inclination, the solar power generation panel can be positioned in an inclined state according to the environment and sunlight conditions of the rooftop on which it is to be installed.

[0023] Furthermore, the floor mounting portion is a metal material having a predetermined length that is placed on the floor surface, and one or both ends of the floor mounting portion are fixed to a predetermined rising portion and are fixed to the panel support portion to support the panel support portion, thereby allowing the foundation portion of the installation structure to be constructed from a metal material having a certain length. Furthermore, even if a vertical or horizontal external force acts on the solar power generation panel, the fixation between the floor mounting portion and the rising portion prevents the solar power generation panel from moving without requiring fasteners or the like to be driven into the floor surface. Furthermore, metal materials, such as steel, are easily available and relatively inexpensive, making it possible to easily construct the foundation portion of the installation structure while reducing installation costs. In this case, placing on the floor does not only mean placing the floor-mounted part directly on the floor, but also includes placing the floor-mounted part by placing a thin plate to fill the gap or a rubber sheet to protect the floor between the floor-mounted part and the floor.

[0024] Furthermore, if the panel support portion is a columnar body to which the solar panel with the lower predetermined slope is fixed, has a lower panel support portion whose one or both ends are fixed to a predetermined rising portion, and multiple floor mounting portions are provided, each of the multiple floor mounting portions is fixed to the lower panel support portion and is arranged in a direction perpendicular to the longitudinal direction of the lower panel support portion, and at least the end of each of the two ends opposite the lower panel support portion along the longitudinal direction is fixed to a predetermined rising portion different from the predetermined rising portion to which the end of the lower panel support portion is fixed, then the area of ​​the solar power generation panel with the lower predetermined slope can be sufficiently fixed by the lower panel support portion and the multiple floor mounting portions.

[0025] Furthermore, if multiple floor-mounted sections are provided, each fixed to a lower panel support section and a higher panel support section, and arranged in a direction perpendicular to the longitudinal direction of the lower panel support section, and at least one of the ends of each floor-mounted section opposite the lower panel support section along the longitudinal direction is fixed to a predetermined rising section different from the predetermined rising section to which the end of the lower panel support section is fixed, the fixing force can be increased against the lift force acting on the solar panel due to wind blowing below the solar panel. That is, in a structure in which the solar panel is arranged at an angle with respect to the floor, airflow infiltrating from a higher position of the solar panel in the direction of gravity to a lower position generates a lift force due to wind pressure. This lift force generates a moment with the lower end of the solar panel in the direction of gravity as a fulcrum. To efficiently suppress this moment, it is necessary to apply the fixing force to the panel support section (higher panel support section) that is higher in the predetermined inclination. Therefore, by fixing the high panel support portion to multiple floor mounting portions and fixing at least one of its ends opposite the low panel support portion to a designated rising portion different from the designated rising portion to which the end of the low panel support portion is fixed, sufficient fixing force can be applied to the panel support portion with the higher designated slope.

[0026] Furthermore, when the panel support is a columnar body to which the solar panel with a lower predetermined inclination is fixed, and one or both ends of the columnar body have a lower panel support fixed to a predetermined rising portion, and when a plurality of floor-mounted sections are provided, and each of the plurality of floor-mounted sections is fixed to the lower panel support and arranged in a direction perpendicular to the longitudinal direction of the lower panel support, they can exert a fixing force on the solar panel in both the vertical and horizontal directions in a planar view. This makes it easier to increase the stability of the floor-mounted sections when they are fixed. Also, the degree of freedom in the arrangement of the floor-mounted sections can be improved.

[0027] In addition, if multiple floor mounting sections are provided and at least one of the floor mounting sections has a metal material of a predetermined length attached to the floor mounting section in a branched manner, with one end of the auxiliary member fixed to a predetermined rising section at a position different from the fixed end of the floor mounting section, the fixing force from not only the floor mounting section but also the auxiliary member is applied, further preventing the solar panel from moving when an external force is applied.

[0028] Furthermore, if the specified rising portion is at least one of a parapet, a structure installed on the floor surface, or a steel material fixed to the floor surface, the floor-mounted portion can be fixed using these structures already installed on the roof of the building. In this context, structures installed on the floor surface include, for example, the walls of a penthouse installed on the roof, concrete pillars or blocks, railings, fences, curb-like structures, and steps such as stairs.

[0029] Furthermore, if the floor-mounted section has a first divided section and a second divided section that are arranged on the same straight line in a plan view, and one end of the first divided section and one end of the second divided section are fixed to predetermined rising sections in different positions, and the other end of the first divided section and the other end of the second divided section are connected by a connecting member, it becomes possible to stably position the floor-mounted section even if the floor of the building has a shape that slopes like a mountain or a valley when viewed from the side.In other words, by placing the first divided section and the second divided section on each side of the floor that has a different slope direction and providing a connecting member at the branch point of the slope (for example, the apex in the case of a mountain-shaped shape), it is possible to stably place the floor-mounted section in accordance with the slope direction.

[0030] In addition, in order to achieve the above-mentioned object, the solar power panel installation method of the present invention is a solar power panel installation method for installing a solar power panel on the floor surface of the roof of a building, and includes a floor installation portion arrangement step of arranging a floor installation portion made of a metal material having a predetermined length on the floor surface and fixing one end or both ends of the floor installation portion to a predetermined rising portion that is fixed to the floor surface and rises upward from the floor surface, and a panel support portion fixing step of arranging a panel support portion that supports the solar power panel at a predetermined inclination above the floor installation portion and fixing it to the floor installation portion.

[0031] Here, in the floor-mounting portion placement step, a floor-mounting portion made of a metal material having a predetermined length is placed on the floor surface, and one or both ends of the floor-mounting portion are fixed to the floor surface and to a predetermined rising portion that rises upward from the floor surface. This allows the metal material having a certain length to be placed on the floor surface and serve as a foundation portion of the installation structure. Furthermore, by fixing one or both ends of the floor-mounting portion to the rising portion, the floor-mounting portion can be provided with fixing force against vertical or horizontal external forces without having to drive fasteners or the like into the floor surface. Furthermore, since metal materials, such as steel, are easily available and relatively inexpensive, it is possible to easily build the foundation portion of the installation structure while reducing installation costs. In this case, placing on the floor does not only mean placing the floor-mounted part directly on the floor, but also includes placing the floor-mounted part with a thin plate to fill the gap or a rubber sheet to protect the floor between the floor-mounted part and the floor.

[0032] Furthermore, in the panel support part fixing process, the panel support part that supports the solar power generation panel at a predetermined inclination is positioned above the floor mounting part and fixed to the floor mounting part, thereby making it possible to position the solar power generation panel and preventing the solar power generation panel from moving via the floor mounting part even if a vertical or horizontal external force acts on the solar power generation panel.

[0033] Furthermore, if the floor-mounting unit placement step involves placing the floor-mounting unit at a position on the floor corresponding to the position of the beams that construct the floor, cracks, damage, etc., on the floor surface due to the load acting in the direction of gravity that occurs when the solar panels, panel support units, and floor-mounting unit are placed on the rooftop floor can be more easily prevented. For example, the rooftop floor of a reinforced concrete building is constructed by integrally pouring a floor slab and strong beams that support the floor slab. Therefore, by placing a heavy floor-mounting unit made of metal material with a certain length at a position corresponding to the internal beams of the floor, the beams can bear the load of the floor-mounting unit, making it less likely that the floor will crack or be damaged even if a load acts on the floor in the direction of gravity. [Effects of the Invention]

[0034] The solar panel installation structure of the present invention does not require any special installation processing on the roof floor when installing on the roof of a building, and can sufficiently prevent solar panels, etc. from moving even if an external force is applied, allowing for stable placement. Furthermore, the method for installing solar panels according to the present invention does not require special processing of the roof floor when installing them on the roof of a building, and can sufficiently prevent the solar panels, etc. from moving even when external forces are applied, making it possible to stably position them.

DETAILED DESCRIPTION OF THE INVENTION

[0036] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0037] [First embodiment of the present invention] A panel installation structure A, which is an example of a solar panel installation structure to which the present invention is applied, includes a mounting base 2 and a support structure 3 (see FIGS. 1 and 2). This panel installation structure A is a structure for installing a solar panel 1 on a rooftop floor 4 of a structure B such as a building.

[0038] In the following description, with reference to Figure 1, the direction of the support structure 3 as seen from the floor 4 will be referred to as "upper" or "upper side," and the direction of the floor 4 as seen from the support structure 3 will be referred to as "lower" or "lower side." Also, with reference to Figure 1, the direction connecting the upper and lower sides will be referred to as the "up-down direction" or "vertical direction."

[0039] In the following description, the left side of the paper in Fig. 1 is referred to as the front, and the right side of the paper in Fig. 1 is referred to as the rear. Also, the direction connecting the front and rear is referred to as the front-to-rear direction.

[0040] In the following description, the direction toward the top of the paper in Figure 2 will be referred to as the right or right side, and the direction toward the bottom of the paper in Figure 2 will be referred to as the left or left side. Also, the direction connecting the left and right sides of Figure 2 will be referred to as the left-right direction. The direction consisting of the front-rear direction or the left-right direction will be referred to as the horizontal direction.

[0041] Here, the mount 2 is a member for mounting the solar panel 1 with the solar panel 1 tilted in a desired direction and supporting the solar panel 1 on the support structure 3. The mount 2 here is a member corresponding to the panel support part in the claims of the present application.

[0042] The support structure 3 is a member that serves as a base when the panel installation structure A is placed on the floor 4. The support structure 3 is also a part that exerts a fixing force to prevent the solar panel 1 from moving in response to external forces applied to the solar panel 1 and the mounting base 2. The support structure 3 referred to here is a member that corresponds to the floor installation portion in the claims of the present application.

[0043] Furthermore, floor 4 is a part that constitutes the roof surface of a building or other structure. This floor 4 is, for example, a reinforced concrete structure, constructed by integrally pouring a floor slab and beams (not shown). Furthermore, a waterproof layer is applied to the surface of the floor slab of floor 4. The floor surface of floor 4 referred to here corresponds to the floor surface in the claims of this application.

[0044] In addition, the mounting base 2 has a front mounting base 20 that supports the area (front area) that is lower in the vertical direction relative to the inclined solar power generation panel 1, and a rear mounting base 21 that supports the area (rear area) that is higher in the vertical direction (see Figures 1 and 2).

[0045] The lower portions of the front and rear bases 20 and 21 are firmly fixed to the support structure 3 by welding, rivets, or bolts and nuts.

[0046] The support structure 3 is a long metal member and is placed directly on the floor 4. As shown in Fig. 2, three support structures 3 are provided along the left-right direction of the solar power generation panel 1.

[0047] Furthermore, both the front end 30 and the rear end 31 of the support structure 3 are fixed to a parapet P provided on the roof floor 4 of the building (see Figures 1 and 2). The parapet P here corresponds to the predetermined rising portion in the claims of the present application. The details of the fixing structure between the support structure 3 and the parapet P will be described later.

[0048] Furthermore, the base 2 and the support structure 3 are made of high-strength metal members such as steel, stainless steel, or aluminum alloy that have been painted or plated to prevent corrosion.

[0049] Here, the shape and structure of the mount 2 are not particularly limited as long as it can support the photovoltaic panel 1 in a state inclined in a desired direction, and any known structure can be adopted.

[0050] Furthermore, the support structure 3 does not necessarily have to be placed directly on the floor 4, and for example, a thin steel plate may be placed on the floor 4 to fill the gap between the support structure 3 and the floor 4, and the support structure 3 may be placed on top of that. Also, for example, a rubber sheet or the like may be placed on the floor 4 to protect the waterproof layer on the surface of the floor 4, and the support structure 3 may be placed on top of that.

[0051] Furthermore, the type of constituent material of the support structure 3 is not particularly limited as long as it has a certain length and is made of a strong metal material. However, since it will be placed outdoors, it is preferable to use metal materials that have been painted or plated (for example, galvanized) to prevent corrosion. Furthermore, by using inexpensive and readily available steel materials such as H-shaped steel, the cost of constructing the support structure 3 can be reduced even if the panel installation structure A is large.

[0052] Furthermore, it is not necessary to provide three support structures 3, and the number of support structures 3 can be selected appropriately according to the size of the solar panel 1 and the mounting base 2, and the installation position on the floor 4.

[0053] Furthermore, it is not necessary for both the front end 30 and the rear end 31 of the support structure 3 to be fixed to the parapet P of the building, and either the front end 30 or the rear end 31 may be fixed to the parapet P. For example, taking into consideration the shape of the rooftop floor 4 and the structures installed on the floor 4, it may be possible to fix only the end that can be fixed to the parapet P. However, from the viewpoint of increasing the fixing force of the support structure 3 to the floor 4, it is preferable that both the front end 30 and the rear end 31 are fixed to the parapet P.

[0054] Furthermore, the object to which the end of the support structure 3 is fixed is not necessarily limited to the parapet P of a building, but any structure that is fixed to the floor 4 and rises above the floor surface of the floor 4 can be used as the object to which the end of the support structure 3 is fixed. For example, the wall of a penthouse installed on the roof, concrete pillars or blocks, railings, fences, curb-like structures, steps and the like, and steel materials installed and fixed to the floor surface can also be objects to which the end of the support structure 3 can be fixed.

[0055] It is also possible to use a combination of multiple types of objects to which the ends of the support structure 3 are fixed. For example, in one panel installation structure A, it is possible to use a combination of multiple types of fixing objects, such as a support structure with its end fixed to the parapet and a support structure with its end fixed to the wall of the penthouse.

[0056] As a variation of the target for fixing the end of the support structure 3, it is possible to select an area of ​​the floor 4 where a waterproof layer is not applied to the surface of the floor slab, and fix the end of the support structure 3 there. Even if fasteners or the like are driven into a floor slab where a waterproof layer is not applied, it is possible to fix the support structure 3 without the need for subsequent waterproofing treatment.

[0057] Next, we will explain the fixing structure between the support structure 3 and the parapet P. As shown in Figures 3(a) and 3(b), a fixing flange 310 is provided at the rear end 31 of the support structure 3. This flange 310 can be made of, for example, a block-shaped steel material.

[0058] The flange 310 is fixed to the rear end 31 of the support structure 3 via a connecting metal fitting (not shown) made of an L-shaped metal plate, a fastener, or the like.

[0059] Then, the vertical wall surface P1 of the parapet P is brought into contact with the flange 310, and the wall surface P1 and the flange 310 are fixed together via fasteners 100 consisting of bolts and nuts. Note that although the rear end portion 31 of the support structure 3 has been described as an example here, the front end portion 30 is also fixed to the parapet P using a similar structure.

[0060] Here, the fixing structure between the support structure part 3 and the parapet P is not limited to fixing via the flange 310, and various structures and methods can be adopted as long as the support structure part 3 and the parapet P can be fixed.

[0061] For example, as shown in Figures 4(a) and 4(b), a configuration can be adopted in which a C-shaped steel 311 is placed and fixed to the upper part of the rear end 31 of the support structure part 3, and this C-shaped steel 311 is fixed to the vertical wall surface P1 of the parapet P with a fixing device 100.

[0062] The C-shaped steel 311 is fixed to the rear end 31 of the support structure 3 via a connecting fitting (not shown) made of an L-shaped metal plate, fastener, or the like. The C-shaped steel 311 is arranged to extend in the left-right direction, and the rear end 31 of multiple support structures 3 can be fixed together to the wall surface P1.

[0063] As another example of a fixing structure, a fixing structure using a fixing ring 101 can be adopted, as shown in Fig. 5(a). A flange 312 for attaching the ring is provided at the rear end 31 of the support structure 3. A hole (reference numeral omitted) through which the fixing ring 101 can be inserted is formed in the flange 312.

[0064] The flange 312 is fixed to the rear end 31 of the support structure 3 via a connecting fitting (not shown) made of an L-shaped metal plate, a fastener, or the like. The fixing ring 101 is a ring-shaped member made of metal.

[0065] An anchor P2 is fixed to the vertical wall surface P1 of the parapet P. A hole (reference numeral omitted) is formed in the anchor P2.

[0066] This anchor fitting P2 is an existing fitting that secures the wires of a gondola or the like when suspending the gondola or the like from the parapet P along the wall surface of a building, for example.

[0067] Here, by inserting the fixing ring 101 into the hole in the flange 312 and the hole in the anchor fitting P2, the flange 312 and the anchor fitting P2 are connected, and the rear end 31 of the support structure part 3 can be fixed to the parapet P.

[0068] Although not shown, another possible structure is to extend the flange 312-shaped block further upward, bring its upper end face to the bottom surface of the horizontally protruding portion of the parapet P, and secure the abutting portion with a connecting metal fitting or the like. With this structure, by securing the upper end face of the block to the bottom surface of the parapet, it is possible to prevent not only horizontal movement of the support structure 3, but also vertical movement.

[0069] In this way, various structures and methods can be adopted for the fixing structure between the support structure part 3 and the parapet P.

[0070] In addition, in the fixing structure between the support structure 3 and the parapet P, it is preferable to take measures to prevent water from entering the fixing parts.

[0071] That is, for example, possible embodiments include applying a waterproof coating to the contact area between the above-mentioned fastener 100 or the like and the wall surface P1 of the parapet P, or providing a rain cover or eaves above the contact area. Another possible embodiment is to use a water-resistant Chemical Anchor (registered trademark) as the fastener. Furthermore, if a waterproof layer is already installed on the surface layer of the wall surface P1 of the parapet P, a possible embodiment is to select an area without the waterproof layer and attach the fastener 100 there.

[0072] Furthermore, as mentioned above, the object to which the end of the support structure part 3 is fixed is not limited to the parapet P, but can also be, for example, the wall of a penthouse installed on the roof, concrete pillars or blocks, railings, fences, curb-like structures, steps such as stairs, or steel materials fixed to the floor surface.

[0073] Furthermore, when fixing the end of the support structure 3, it is not necessary to fix the end of the support structure 3 to the vertical surface of the structure to be fixed, but it is also possible to fix the end of the support structure 3 using the horizontal surface of the structure to be fixed. For example, if a concrete staircase is provided on the floor 4, it is also possible to fix the horizontal surface of the staircase and the end of the support structure 3 with connecting metal fittings or the like.

[0074] 5(b), a reinforcing block 314 may be provided at the end of the support structure 3 to further suppress horizontal movement. A flange 313 is provided on the upper part of the rear end 31 of the support structure 3, and the flange 313 is fixed to the parapet P via a fixing device 100.

[0075] In addition, below the flange 313, a reinforcing block 314 having a U-shape in plan view is provided and fixed to the parapet P. The reinforcing block 314 has a recess 314a formed therein that is slightly larger than the outer edge of the rear end 31 of the support structure 3.

[0076] With this reinforcing block 314, even when a horizontal external force acts on the support structure 3, the recess 314a functions to restrain the horizontal movement of the end 31, thereby further improving the horizontal fixing force in addition to the fixing force provided by the fixing device 100.

[0077] In the panel installation structure A described above, when installing the solar power generation panel 1 on the floor 4, the support structure 3 serves as the foundation, allowing the solar power generation panel 1 and the mounting base 2 to be installed stably on the floor 4.

[0078] Furthermore, since the support structure 3 is placed on the floor 4 and its ends are fixed to the parapet P, the support structure 3 can be given a fixing force without having to drive fixing devices or the like into the floor 4.

[0079] That is, the support structure 3 can sufficiently prevent the solar panel 1 from moving even when a horizontal or vertical external force acts on the solar panel 1 and the mount 2.

[0080] In addition, the support structure 3 can be constructed using a certain length of metal material, and since there is no need to use special materials or construction methods to install or fix the support structure 3, it has a simple structure and can reduce installation costs.

[0081] [Second embodiment of the present invention] A second embodiment of the present invention will be described. In the following, the same components as those in the first embodiment of the present invention will be denoted by the same reference numerals, and the description thereof will be omitted.

[0082] The panel installation structure B, which is the second embodiment of the present invention, comprises a mount 2 and a support structure 3B (see FIG. 6). The main difference between the second embodiment of the present invention and the first embodiment of the present invention is the structure of the support structure 3B and the fixed positions of its ends.

[0083] The support structure 3B shown in Fig. 6 is disposed in front of the solar panel 1 and has one lower panel support 32 extending parallel to the left and right direction, and four support structure 33 extending parallel to the front and rear direction. The mount 2 is composed of a front mount 20 and a rear mount 21. The lower panel support 32 and the front mount 20 are an integrated columnar member.

[0084] The lower panel support 32 and the front base 20 are members that correspond to the lower panel support in the present claims, and the rear base 21 is a member that corresponds to the high panel support in the present claims. Also, the support structure 33 is a member that corresponds to the multiple floor surface installation section in the present claims.

[0085] The lower panel support portion 32 is formed to have a length such that a right end portion 320 thereof reaches the right parapet P3 of the building located to the right of the position where the photovoltaic power generation panel 1 is arranged.

[0086] That is, the lower panel support portion 32 is a member whose right end portion 320 is fixed to the parapet P3 and which exerts a fixing force that prevents the photovoltaic panel 1 from moving.

[0087] The four support structures 33 are arranged in a direction perpendicular to the lower panel support 32. The four support structures 33 have their upper portions fixed to the lower panel support 32 and the front frame 20 on the front side of the solar panel 1, and their upper portions fixed to the rear frame 21 at the position of the rear frame 21.

[0088] The four support structure parts 33 are formed to have a length such that the rear ends 330 reach the rear parapet P4 of the building located on the rear side of the position where the photovoltaic power generation panel 1 is arranged.

[0089] That is, each support structure 33 has a rear end 330 fixed to the rear parapet P4, and is a member that exerts a fixing force that prevents the photovoltaic panel 1 from moving.

[0090] The various fixing structures already mentioned can be used for the fixing structure between the right end 320 of the lower panel support 32 and the parapet P3, and the fixing structure between the rear end 330 of the support structure 33 and the parapet P4. The same applies to the fixing between the end of the support structure and the parapet, which will be described below.

[0091] Here, in the panel installation structure B, the support structure part 33 is fixed to the rear side frame 21 in the area behind the solar power generation panel 1, and the rear end part 330 is fixed to the rear parapet P4, so that the fixing force can be increased against the lift force acting on the solar power generation panel 1 when wind blows below the solar power generation panel 1.

[0092] More specifically, in a structure in which the solar panel 1 is arranged at an incline with respect to the floor 4, an air current invading from a higher position (rear) of the solar panel 1 in the direction of gravity to a lower position (front) generates lift due to wind pressure, and a moment acts with the lower end side as a fulcrum. In order to efficiently suppress this moment, it is necessary to apply a fixing force to the rear frame 21, which is located on the higher side of the specified inclination.

[0093] Therefore, by fixing the rear frame 21 to the support structure 33 and fixing the rear end 330 of the support structure 33 to the rear parapet P4, it is possible to provide sufficient fixing force to the solar power generation panel 1 and rear frame 21 that have a higher predetermined inclination. In other words, it is possible to efficiently increase the fixing force against the lift force.

[0094] Furthermore, in the panel installation structure B, the right end 320 of the lower panel support part 32 is fixed to the parapet P3, so that a fixing force can be applied to the solar power generation panel 1 with a lower predetermined inclination. In addition, combined with the fixing force of the support structure part 33, it is possible to prevent the solar power generation panel 1 and the mounting frame 2 as a whole from moving in the horizontal direction.

[0095] Furthermore, in the panel installation structure B, the lower panel support 32 and the front frame 20 are arranged to extend in the left-right direction, and the support structure 33 is arranged to extend in the front-rear direction relative to the solar power generation panel 1. Therefore, in a plan view, a fixing force can be exerted on the solar power generation panel 1 in both the left-right direction and the front-rear direction. Fixing in these two orthogonal directions can increase the stability of the solar power generation panel 1 in a fixed state.

[0096] Furthermore, in panel installation structure B, the right parapet P3 and rear parapet P4 are targets for fixing the lower panel support part 32 or the support structure part 33. In other words, different parapet positions are used for fixing than in the above-described panel installation structure A. In this way, in the present invention, it is possible to appropriately set the positions for fixing the ends of the support structure parts according to the structure of the rooftop floor of the building where the solar power generation panel 1 is to be installed and the installation position of the solar power generation panel 1.

[0097] Furthermore, the number of lower panel support portions 32 provided does not necessarily have to be one, and the number of support structure portions 33 provided does not necessarily have to be four. The numbers of lower panel support portions 32 and support structure portions 33 can be set as appropriate.

[0098] Furthermore, the structure is not necessarily limited to one in which the right end 320 of the lower panel support portion 32 is fixed to the right parapet P3. For example, it is also possible to employ a configuration in which both the left and right ends of the lower panel support portion 32 are fixed to the parapet, or a configuration in which only the left end of the lower panel support portion 32 is fixed to the parapet.

[0099] Furthermore, the structure is not necessarily limited to one in which the rear end 330 of the support structure 33 is fixed to the rear parapet P4. For example, it is also possible to adopt a structure in which both the front and rear ends of the support structure 33 are fixed to the parapet, or a structure in which only the front end of the support structure 33 is fixed to the parapet.

[0100] Furthermore, as a modification of the second embodiment of the present invention, a structure may be adopted in which, in relation to the arrangement of the solar power generation panels 1 in Fig. 6, multiple support structures extending in the left-right direction are provided, with the right ends of each fixed to the parapet P3, and a part of the mounting base 2 is structured to extend in the front-rear direction, with the rear end fixed to the parapet P4. In other words, a structure may be adopted in which the longitudinal directions of the support structures 33 and the lower panel supports 32 in Fig. 6 are reversed by 90 degrees.

[0101] [Third embodiment of the present invention] A third embodiment of the present invention will be described below. In the following, the same components as those in the first and second embodiments of the present invention will be denoted by the same reference numerals, and the description thereof will be omitted.

[0102] The panel installation structure C, which is the third embodiment of the present invention, comprises a mount 2 and a support structure 3C (see FIG. 7). The main differences between the third embodiment of the present invention and the first and second embodiments of the present invention are the structure of the support structure 3C and the inclusion of an auxiliary support structure 35.

[0103] 7 has four support structures 34 extending parallel to the front-to-rear direction. Of the four support structures 34, the rightmost support structure 34 and the leftmost support structure 34 have auxiliary support structures 35 branching off from a position slightly forward of the rear end 340.

[0104] The auxiliary support structure 35 here corresponds to the auxiliary member in the claims of the present application.

[0105] The upper part of this support structure 34 is fixed to the front frame 20 and the rear frame 20, and the rear end 340 is formed to a length that reaches the rear parapet P4 of the building located rearward of the position where the solar power generation panel 1 is placed.

[0106] That is, each support structure 34 has a rear end 340 fixed to the parapet P4, and is a member that exerts a fixing force that prevents the photovoltaic panel 1 from moving.

[0107] In addition, one end 350 of each of the two auxiliary support structures 35 is attached to the corresponding support structure 34 in a branched manner, and the other end 351 is fixed to the rear parapet P4 at a position different from the rear end 340 of the support structure 34.

[0108] The other end 351 of this auxiliary support structure 35 is fixed to the rear parapet P4, so that it serves as a member that reinforces the fixing force of the support structure 34.

[0109] In this panel installation structure C, the rear end 340 of the support structure 34, fixed to the rear parapet P4, exerts a fixing force that prevents the solar panel 1 from moving, but of the four directions (front-to-back and left-to-right), only the rear parapet P4 is used for fixing.

[0110] In other words, the fixing force of the support structure 34 is weaker than in a configuration in which parapets are used to fix the structure in two or more of the four directions (front-rear and left-right). Therefore, by also using the auxiliary support structure 35 to improve the fixing force, the structure can have sufficient fixing force even when fixed only by the rear parapet P4.

[0111] Here, it is not necessarily required that the auxiliary support structure 35 is provided on only two of the four support structures 34. For example, a structure in which an auxiliary support structure 35 is provided on each of three or four support structures 34 may be used. Alternatively, a structure in which an auxiliary support structure 35 is provided on only one support structure 34 may be used.

[0112] Furthermore, the other end 351 of the auxiliary support structure 35 does not necessarily have to be fixed to the rear parapet P4. For example, a structure may be employed in which the other end 351 of the auxiliary support structure 35 is fixed to the right parapet P3 of the building to the right of the arrangement position of the photovoltaic panel 1.

[0113] [Fourth embodiment of the present invention] A fourth embodiment of the present invention will be described. In the following, the same components as those in the first, second, and third embodiments of the present invention will be designated by the same reference numerals, and the description thereof will be omitted.

[0114] A panel installation structure D according to a fourth embodiment of the present invention includes a mount 2 and a support structure 3D (see FIG. 8).

[0115] The main difference between the fourth embodiment of the present invention and the first, second, and third embodiments of the present invention is the structure of the support structure 3D, which is designed to enable stable installation on a floor 40 made up of multiple floor surfaces with different slopes.

[0116] 8, floor 40 has an inclined surface 400 inclined from the rear toward the front in a side view, and an inclined surface 401 inclined from the front toward the rear in a side view. In other words, floor 40 has a mountain-like shape in a side view.

[0117] Furthermore, the support structure 3D has a first divided support structure 36 arranged corresponding to the inclined surface 400, and a second divided support structure 37 arranged corresponding to the inclined surface 401. Furthermore, the rear end of the first divided support structure 36 and the front end of the second divided support structure 37 are connected by a connecting member 38.

[0118] In Figure 8, due to the drawing configuration, only one set of the first divided support structure 36 and the second divided support structure 37 is disclosed, but in the panel installation structure D, multiple sets of the first divided support structure 36 and the second divided support structure 37 are arranged along the left-right direction (not shown).

[0119] The first divided support structure 36 referred to here is a member that corresponds to the first divided portion in the claims, and the second divided support structure 37 is a member that corresponds to the second divided portion in the claims. The connecting member 38 referred to here is a member that corresponds to the connecting member in the claims.

[0120] The first divided support structure 36 has an upper portion fixed to the front frame 20, and a front end portion 360 fixed to a parapet P on the front side of the floor 40. The second divided support structure 37 has an upper portion fixed to the rear frame 21, and a rear end portion 370 fixed to a parapet P on the rear side of the floor 40.

[0121] That is, one end of the first divided support structure 36 and the second divided support structure 37 is fixed to the parapet P, and the other ends are connected to each other via a connecting member 38, thereby exerting a fixing force that prevents the solar power generation panel 1 from moving.

[0122] Furthermore, connecting member 38 is a known connecting metal fitting, and is configured, for example, with a flat or L-shaped metal plate and a fastener, etc. Furthermore, as shown in Fig. 8, connecting member 38 is disposed at the boundary portion between inclined surface 400 and inclined surface 401 on floor 40 (the portion corresponding to the apex of the mountain shape in plan view).

[0123] In this panel installation structure D, the support structure 3D is divided in the front-to-rear direction into a first divided support structure 36 and a second divided support structure 37 and placed on the floor 40, making it possible to stably install the support structure 3D on a floor 40 made up of multiple floor surfaces with different slopes.

[0124] Furthermore, in the example shown in Figure 8, floor 40 has inclined surfaces 400 and 401 that form a mountain-like shape when viewed from the side, but support structure 3D can also be stably installed on a floor that forms a valley-like shape when viewed from the side.

[0125] [Fifth embodiment of the present invention] A fifth embodiment of the present invention will now be described. This fifth embodiment has a distinctive structure in terms of the position of the support structure relative to the floor.

[0126] As shown in Figure 9, the panel installation structure E of the fifth embodiment of the present invention has a support structure 39a parallel to the left-right direction, two medium-length support structure parts 39b parallel to the front-rear direction, and two long support structure parts 39c parallel to the front-rear direction. One or both ends of each support structure part are fixed to the parapet (reference numbers omitted).

[0127] As shown in FIG. 9, a floor 41 of a building has a floor slab 410 and a plurality of beams 411 and columns 412 that support the floor slab 410 therein.

[0128] In this panel installation structure E, two long support structure portions 39c are arranged at positions corresponding to the beams 411 of the floor 41.

[0129] That is, the structure employs an arrangement in which the load of the support structure part 39c is supported by strong beams 411 that support the floor slab 410. This makes it possible to make the floor 41 less likely to crack or break even if a load is applied to it in the direction of gravity.

[0130] [Sixth embodiment of the present invention] A sixth embodiment of the present invention will be described. In this sixth embodiment, an existing solar power generation panel 1A is installed on the roof floor of a building, and a solar power generation panel 1B is added next to it.

[0131] First, when installing solar panels, there are cases where existing solar panels are installed on the roof floor of a building, and additional solar panels are added later.

[0132] As shown in FIG. 10, the existing solar power generation panel 1A has a mount 11A that supports the solar power generation panel 1A, and a dedicated concrete foundation 10A that supports the mount 11A.

[0133] This dedicated concrete foundation 10A is provided integrally with the floor slab that forms the rooftop floor 42, and the mounting base 11A is fixed to the dedicated concrete foundation 10A via anchor bolts, etc. In other words, the existing solar power generation panel 1A has had the dedicated concrete foundation 10A provided from the beginning of construction.

[0134] In addition, in the panel installation structure F according to the sixth embodiment of the present invention, a photovoltaic power generation panel 1B is added to an area of ​​the floor 42 where the dedicated concrete foundation 10A is not present.

[0135] This panel installation structure F has a mount 11B that supports a photovoltaic power generation panel 1B, and a support structure part 300 that supports this mount 11B.

[0136] The mount 11B is connected to the mount 11A and is disposed on an extension of the mount 11B in the longitudinal direction. The support structure 300 is disposed in a direction perpendicular to the mount 11B, and the upper part of the support structure 300 is fixed to the mount 11B at the position where it intersects with the mount 11B.

[0137] In addition, both ends of the support structure 300 are fixed to a parapet P5 provided on the floor 42.

[0138] In this panel installation structure F, a solar power generation panel 1B to be installed later is added to an existing solar power generation panel 1A that has been installed on a dedicated concrete foundation 10A, using its mounting base 11A.

[0139] Furthermore, in the panel installation structure F, the support structure 300 serves as a base, and its ends are fixed to the parapet P5, thereby exerting a fixing force that prevents the solar power generation panel 1B from moving. In this way, the panel installation structure F can be used in a manner in which solar power generation panels are added later.

[0140] As described above, the installation structure for solar panels to which the present invention is applied does not require any special installation processing on the roof floor when installing solar panels on the roof of a building, and can sufficiently prevent solar panels, etc. from moving even if an external force is applied, allowing them to be placed stably. Furthermore, the method of installing solar panels to which the present invention is applied does not require special installation processing on the roof floor when installing solar panels on the roof of a building, and is a method that can sufficiently prevent solar panels, etc. from moving even if an external force is applied, allowing for stable placement.

[0141] The terms and expressions used in the present specification and claims are merely for explanatory purposes and are not limiting in any way, and are not intended to exclude terms and expressions equivalent to the features described in the present specification and claims and parts thereof. It goes without saying that various modifications are possible within the scope of the technical idea of ​​the present invention. [Explanation of symbols]
